On Wednesday, at least 24 civilians were killed in strikes on Yemen 's Hodeida province, the Red Sea district at the heart of a fight between a regional military alliance led by Saudi Arabia and Yemen 's Iran-backed Huthi rebels.

Among the locations hit was a facility where labourers were packing vegetables, the United Nations said.

In September alone, the country was hit by at least 154 air raids, according to the Yemen Data Project.

Children have been killed in air strikes, while blockades and corruption leave entire cities unable to find food and clean water.

Saudi Arabia is now under nearly unprecedented scrutiny following the murder this month of Khashoggi, the former royal court insider-turned-critic who wrote a column for the Washington Post.

But analysts say it is unlikely the Khashoggi killing will turn the spotlight on Saudi Arabia 's broader policies -- leaving Yemenis fighting to survive war, famine and a failed economy that may prove as fatal as the violence.
